Detailed Description

The location feature stores the location of an (normally) node or area.

Even the data is not stored the location feature checks that a street or place and an house number is stored on the object.

So in effect it stores the location part of objects that have an address.

Member Function Documentation

AllocateValue()

FeatureValue * osmscout::LocationFeature::AllocateValue ( void *  buffer )

overridevirtual

Reimplemented from osmscout::Feature.

GetName()

std::string osmscout::LocationFeature::GetName ( ) const

overridevirtual

Returns the name of the feature.

Implements osmscout::Feature.

References NAME.

GetValueAlignment()

size_t osmscout::LocationFeature::GetValueAlignment ( ) const

overridevirtual

If feature have value object, this method returns alignment requirements of the value type (alignof( type-id )).

Reimplemented from osmscout::Feature.

GetValueSize()

size_t osmscout::LocationFeature::GetValueSize ( ) const

overridevirtual

A feature, if set for an object, can hold a value.

If there is no value object, this method returns 0, else it returns the C++ size of the value object.

Reimplemented from osmscout::Feature.

Initialize()

void osmscout::LocationFeature::Initialize ( TagRegistry &  tagRegistry )

overridevirtual

Does further initialization based on the current TagRegistry.

For example it registers Tags (and stores their TagId) for further processing.

Implements osmscout::Feature.

References osmscout::TagRegistry::RegisterTag().

Parse()

void osmscout::LocationFeature::Parse ( TagErrorReporter &  reporter, const TagRegistry &  tagRegistry, const FeatureInstance &  feature, const ObjectOSMRef &  object, const TagMap &  tags, FeatureValueBuffer &  buffer  ) const

overridevirtual

Implements osmscout::Feature.

References osmscout::FeatureValueBuffer::AllocateValue(), osmscout::FeatureInstance::GetIndex(), and osmscout::LocationFeatureValue::SetLocation().
